What Should You Know Before Adding Solar Panels to an Existing System? 

Upgrading your solar panel system can be a complicated procedure. That’s why you should know all the details to make an informed decision about your energy needs and production.

Energy Needs 

The first reason for you to expand your solar panel system is that your current system is not giving you enough power output that your home or office needs. At this point, it is wise to determine how much energy is needed for your space daily and then decide on how many more solar panels must be additionally installed in the existing system. Energy needs may vary for everyone, and they may increase over time. Adding more solar panels can increase your power output and fulfil your energy needs.

Space for New Solar Panels 

Checking for a suitable and adequate space is a must when adding solar panels to a current system. If you have a rooftop solar panel system, it is better to ensure, that the roof has the strength to hold the weight of the additional solar panels. In simple words, the roof must be strong enough, with a considerable amount of free space! So, what if your roof does not have enough space for new solar panels? you can always choose free-standing solar panels or ground mounted solar panels which have their advantages and disadvantages.

Equipment Compatibility during Upgrades 

Solar Panel: While introducing new solar panels, it is essential to check if they are compatible with the current system. It is best to choose the same or a similar brand to the existing solar panel systems to avoid any technical difficulties. On that note, do not forget to get a maintenance check of the old system while the new ones are being installed. Do check all equipment and the wiring to ensure maximum efficiency.

Inverter: One main thing to keep in mind is that inverters may need to be upgraded when you are adding more panels to the current system. When your solar panel systems are upgraded, the entire system produces much more electrical power where the inverter has to convert more Direct current (DC) into Alternative Current (AC) for your use. You should make sure the inverter can do this to reduce energy loss. So, what are the options? If your original inverter cannot handle the capacity, you can install a new inverter so that all the power is converter through one inverter. You also can install a new inverter for the new solar panels alone, which means you will need new set of batteries and wiring systems. So, you will have two inverters for your entire system.

Permit: When you are adding more solar panels to your current system, you must make sure you have the necessary documentation for it. You must have the permit and interconnection application within the regional area, with clear specifications such as the number of panels, inverter capacity details, energy output. The one thing to note here is that you may not be eligible for the same tax credits as before. Your solar installer will provide you with a clearer picture.
